Waiver to Allow Hospitals to Use the NFPA 6-Year Damper Testing Interval

This memorandum permits hospitals to apply the NFPA 6-year testing interval for fire and smoke dampers in hospital heating and ventilating systems, so long as the hospital's testing system conforms to the testing requirements under the 2007 edition of NFPA 80 and NFPA 105. Hospitals may operate under the damper testing cycle of the NFPA 2007 edition without special application to CMS.
